To all whom it may concern: 7

Be it known that 1, CHARLES A. NELSON, a citizenof the United States,residing at Utica, in the county of Oneida and State of New York, haveinvented certain new and useful Improvements in Firearms, of which thefollowing is a specification.

This invention relates toguns and 'parconstruction and reduce the costof manufacture, facilitate assembling and disassemthe gun.

bling of theparts, increase theelement of safety. inthe handling of thegun, and post the user at all times as to the condition of W Theinvention will be found fully illus tratedin the accompanying drawings,wherein, a

Figure 1 is aleft side elevation, of the improved gun, partly insection; Fig. 2 is a rightqside elevation, the breech-bolt being lookedback; Fig. 3 is a fragmentary right side elevation, illustratingparticularly the means for looking back the breech-bolt; Fig. 4 is aplan of the frame,- with the breechbolt removed; Fig. 5 and Fig.'Gdetail's illus-' trative of a modification of said means; Figs. ,7: to10, inclusive, details illustrative of the grip-safety means; and, Fig.11 a front fragmentary elevation of the grip.

Except as hereinafter indicated the fol-- lowing parts of the gun shownin said drawingsare or may be all substantially theisame parts of thegun set wit: the frame a havingthe depending gripforming portion a, thesliding breech-bolt 6 having the removable breechlug 0 containingthefiring pin (not shown the hammer d and the-sear e, the barrel f, thespring 9 for returning the breech-bolt after recoil, the sear trip (ortrigger and sear connector) I, the trigger i, the magazine j and itsspring-elevated platformk, and the magazine catch Z. p v

Specification of Letters Patent. 1 Patented Jan, 11 1916, Applicationfiled June 22, 1914. Serial No. 346,457.

For preventing double-firing in the present case the sear trio it has arigid toe h which, when a pull on the triggerbrings it against thevertical face of a fixed shoulder on the gun frame and this results inthe discharge of the arm and is followed by the depression of thesear-trip under the wiping action of the rearwardly sliding breech-bolt,

snaps under the shoulder and locks downthe sear-trip out of the path ofthe (cooked) sear in the ensuing return of the breech-bolt underpressure of springg. This construc: tion simplifies the sear trip,insures much greater, reliabilitv of the action thereof and makes itbetter adapted to withstand wear and tear, it being noted that theelasticity of the flesh ofthe users finger afi'ordsthe necessary impetusto the sear trip to cause it to catch under the shoulder k' In theimproved grip safety mechanism, a lever on at the back of, and shaped toconform with the contour of, portion a of the gun frame to formtherewith the grip is fulcrumed on a transverse pin n in an openmg 0,its outward movement being limited by contact of a lug p at its upperend with the back wall of the portion a. Another lever, g, having ahorizontal loop-shaped portion 7 embracing the magazine and a dependingangular leg 9" formed with'the lrnee 7 is fulcrumed on the transverse pm8. its forward end having a lug which (marked t) bears down on thesurface a of the frame on which the trigger slides, abutting the triggerand so normally preventing its rearward movement. The lever m receivesthe contact of the kneeg' on its (hollow) inner side. The parts arenormally held in the positions described by a spiral spring '0 coiledaround a sleeve to onpin n and having one end engaged in the frame andthe'other bearing against the forward side of leg g of lever q. Theloop-shaped portion-of lever 19 contacts with the sides of the magazinecavity of the frame, so that sidewise movement of said. lever isprevented.

To similarly preserve the lever m against lost-motion I provide itsupper end with the slotted jaws m which fit nicely between and incontact with the fulcrum portions g of the lever g, the slots ofsaidjawsv receivingthe pin 8. -When the gun is properly gripped in the actof'pulling the trigger theincidenvtion when the grip is relaxed.

tal forward pressure on lever m obviously elevates the lug t on lever gout of the path of rearward movement of the trigger, sprmg 'u returningthe parts to their normal POSI- In the right side of the frame, underthe breech-bolt, is an upwardlyopen elongated longitudinally extendinghousing or groove :0 which enters the magazine cavity at the rear andhas an aperture a? leading to 1ts front end. A bar or lever 3 has a knee3 on which it rests, in a manner adapting 1t to tilt, on the bottom ofthis groove or housing; the top of the bar 3 slopes toward each end froma point near the middle 'thereof, where it is adapted to have a fulcr umon the under side of the breech-bolt, whlch, when in place, confines thebar in said groove. The forward end of the bar kept normally uplifted bythe spring 2, as a finger-piece 2, and its rear end, which overlies themagazine platform and is adapted to be elevated thereby as soon as thelast cartridge is withdrawn from the magazine,

has a toe 3 adapted to enter a locking notch 4 in the under side of thebreech bolt upon rearward movement incident to firing the lastcartridge, thus locking the breech-bolt in an abnormal position and sosignifying that the magazine is empty; to release the breech-bolt,having replaced the empty magazine with a filled one, the operatorpresses upwardly with his trigger finger against the finger piece 2,which protrudes through aperture :0. The front ends of the housing andbar are formed rearwardly inclined, as at'm" y", and the barhas alateral pin 5 received in a forwardlyvinclined groove 6 in one side ofthe housing 00. With this construction, due to the convergence of thesurface w and groove 6, the barcannot be removed except by holding downits forward end and elevating its rearward end, in which manner it maybe removed readily. In the present instance, the forward thrust of thebar under pressure of the breech-bolt is assumed by the pin 5 engagingthe forward side of the groove 6.

In Figs. 5 and 6 the construction is substantially the same exceptingthat the front end of the bar, contacts with the front end of thehousing 00* on assuming the thrust of the breech-bolt and that a spring7 carried by the bar and held compressed between the same at one side ofthe housing serves both to retain the bar in the position to which it ismanually rocked (so long as the upward pressure of the magazine platformis absent) and to keep the bar from being dislodged when the gun istaken down. I

The pin 8 affording a fulcrum for the magazine catch Z is in the presentarm loosely or revolubly mounted in the frame and has a driving fit inthe magazine catch.

customarily, the pin has a driving fit in the 1 and including ertedlongitudinally of the what I claim as new and desire to secure byLetters Patent is: v
